the thick wall in the combustion chamber, discharging a

strong jet of hot gases inside it.

The high speed of the combustion gases ensures

excellent temperature uniformity and high efficiency of the

system, which improves the product quality. The gas

velocity can reach 328 ft/sec (100 m/s). There are different

nozzle lengths ranging from 31 inches (800mm) to 55

inches (1,400mm).

Burner Specifications:

• Control options include on/off or group modulation

and pulse firing. Constant air flow.

• Self ignition by process temperature.

• Flame detection is not necessary (Temperature

above 1382ºF or 750ºC).

Installation

Eclipse ExtensoHeat Lance Burners, V1, Installation Guide 235, 5/23/2011

Checklist Before Installation

Intake

To admit fresh combustion air from outdoors, provide an

opening in the room of at least one square inch per 3,000

BTU/hr (5 cm

per 1 kW). If there are corrosive fumes or

materials in the air, supply the burner with clean air from

an uncontaminated area, or provide a sufficient air filtering

system.

Exhaust

Do not allow exhaust fumes to accumulate in the work

area. Provide some positive means for exhausting fumes

from the furnace and the building.

Access

Make sure you install the burner in such a way that you

can gain easy access for inspection and maintenance.

Environment

Make sure the burner operating environment matches the

original operating specifications. Check the following

items:

• Voltage, frequency and stability of the electrical

power

• Type and supply pressure of the fuel

• Availability of enough fresh, clean combustion air

• Adequate oxygen concentration for combustion on

the process gases

• Humidity, altitude and temperature of the air

• Presence of damaging corrosive gases in the air

General Installation Conditions

Mechanical

Connect the burner feedings with the corresponding

manifold using steel piping, or copper in special cases.

Weld in accordance with both the country’s regulation

where the equipment will be installed, and user specific

standards as applicable.

Check the following before installing the burner:

• Remove all dirt (dust and other particles) and avoid

further soiling during piping and accessory

installation.

• Check that there are no obstructions in the burner

duct or in the feed piping connections.

Electrical

Install the high-voltage transformer (as applicable) as

close to the burner as possible.

■ Take special care with control and measurement

wiring installation and insulation, which must be

protected against moisture, electrical induction,

etc., while still insuring correct installation

grounding.

Burner Installation

Dimensions

For full information on the dimensions, refer to the specific

datasheet.

Chamber Wall

Make sure the chamber’s wall or roof is strong enough to

support the weight of the burner. If necessary, reinforce

the area where you plan to install the burner to support the

weight of the burner.

Avoid Losses

To make sure air does not go back to the casing of the

chamber, it is important that the joint between the roof and

the burner plate is sealed with some type of insulation,

such as ceramic fiber.

WARNING

Eclipse ExtensoHeat Lance Burners, V1, Installation Guide 235, 5/23/2011

Figure 3.1. ExtensoHeat Burner Installation on the

Chamber Roof (Dimensions in mm)

The front plate is supported on the roof and enables the

burner to be fixed in place with a retainer ring. The sliding

securing system allows each burner to be adapted to the

kiln wall or roof thickness where it is installed.

Figure 3.2. ExtensoHeat Burner Front Plate

The hole diameter through the kiln’s roof allows

ExtensoHeat burners to be installed in case of low

temperature level.

Figure 3.3. ExtensoHeat Burners Distribution

The front plate includes a flame viewport with manual

latch. There is a fixation option with a ball, which enables

the burner to be orientated within a ten degrees angle, that

is available under request.

Installation Conditions

• Check that the burner extension tube is at least 7.9”

(200mm) longer than the wall thickness to allow the

installation of the front supporting plate.

• Measure the kiln roof or wall thickness and then

install the retainer ring so the end of the nozzle is

even with interior surface of the kiln roof/wall, or

recessed up to a maximum of 2 inches (50mm).

Eclipse ExtensoHeat Lance Burners, V1, Installation Guide 235, 5/23/2011

■ Adjust the length of each burner seperately in arch

kilns.

• Settle the front plates on their housings.

• Install the burners in the kiln taking precaution to

firmly tighten the locking wing nuts in the neck of the

front plate.

• The securing rings on the side burners (horizontal

position) have to be replaced with sliding flanges

that are to be welded in place with a length suitable

to the wall thickness.

Piping

Layout

Install the piping as shown in the schematics. Refer to

Design Guide 235.

Support the Piping

Use bar supports with height adjustment to support each

group of gas and air piping. Consult your local gas

company with questions.

Pipe Connections

1. Install a pipe union in the gas line to the burner. This

simplifies removal of the burner.

2. The use of flexible pipe nipples in the gas line to the

burner is the most common. Flexible nipples can

absorb stress due to heat expansion and slight

misalignment.

■ Flexible pipe nipples may cause higher pressure

drops than an equivalent standard pipe. Consider

this when you size the air and gas lines.

Avoid Large Pressure Drops

NOTE: The pressure drop of the gas in the piping is a

critical parameter. Make sure the size of all piping is large

enough to prevent excessive pressure losses.

Valve Installation

Valve Orientation

Install all the valves in such a way that the arrow (if

present) on the valve body points in the direction of flow.

Gas Cocks

Make sure the handle of the gas cock is at a right angle to

the valve body when the valve is in the closed position.

This is an important position indicator. If you do not do this,

somebody may think that the gas cock is in the closed

position, when it is actually in the open position.

Gas Balancing Valves

A gas balancing valve is typically the same as a manual

butterfly valve. For more information, refer to the section

below.

Manual Butterfly Valves

Install manual butterfly valves in accordance with Bulletin/

Info Guide 720.

Automatic Butterfly Valves

An automatic butterfly valve is driven by an actuator

(actuator and mounting bracket not illustrated). Install the

control valve in accordance with Bulletin/Info Guide 720.

Adjustable Limiting Orifices

Adjustable limiting orifice valves are used for fine

adjustment of gas flow. Install the control valve in

accordance with Bulletin/Info Guide 728/730.

Solenoid Valves

Install special solenoid valves for use in pulse control

systems in accordance with the manufacturers

information.

High Pressure Control Valves

Install high pressure gas control valves as specified in the

manufacturer’s installation manual.

Checklist After Installation

To verify proper system installation, do the following:

1. Make sure there are no leaks in the fuel lines or the air

lines.

2. Make sure all the components of the control system

are properly installed. This includes verifying that all

switches are installed in the correct location and that

the wiring, pressure lines and impulse lines are

properly connected.

3. Make sure the blower rotates in the correct direction. If

incorrect, have a qualified electrician rewire the blower

to reverse its rotation.

4. Make sure all valves are installed in their proper

location and correctly oriented relative to the gas or air

flow direction.

5. Make sure all safety components are installed and

working properly.

NOTICE

Adjustment Start & Stop

Eclipse ExtensoHeat Lance Burners, V1, Installation Guide 235, 5/23/2011

Figure 4.1. Air Adjustment

6. Using a manometer, adjust the low-pressure switch air

circuit to 50% of the blower pressure.

7. Adjust the air line bypass to maintain a minimum

cooling airflow when the air valve is closed

NOTE: Make sure the blower rotates in the correct

direction. If incorrect, have a qualified electrician rewire

the blower to reverse its rotation.

Step 2: Fuel Gas Adjustment and

Regulation

1. Check the gas pressure of selected nozzles on the

application.

2. Adjust the gas pressure at the entrance of the group of

burners so it corresponds with the pressure level stated

in Datasheet 235-1.

3. Adjust the low pressure switch of the gas line to 50-

70% of the required inlet pressure.

4. Adjust the high-pressure switch of the gas line to 20%

above the inlet pressure to the burners.

5. Fully open the manual gas valve.

6. Fully open the gas balancing valve to the burner.

Figure 4.2. Fuel Gas Adjustment

7. Use the gas curves from the appropriate ExtensoHeat

datasheet for the gas being used to find the gas

pressure needed at high fire. This is the target value for

high fire.

8. Adjust the gas pressure regulator to achieve the target

value.

9. Adjust the minimum pressure of the gas bypass to 10%

of the high fire pressure or lower if necessary to prevent

product damage during cycle advances (if it exists).

10. Repeat steps 3 and 4 for all burners of the group.

Step 3: Air Balancing Adjustment

Adjust the air balancing valve again for each burner to

keep the pressure at the selected value (4-6 “w.c. or 10-

15 mbar at Tap A)

Step 4: Settings Verification

After several operation cycles, check the chamber

temperature homogeneity, and, if necessary, adjust the

gas by adjusting the manual balancing valves for each

burner separately.

NOTE: When all the settings have been completed, mark

the position of the indicator, or lock the balancing valves

to hold the valve position.

■ If simulated limits do not shut down the fuel

system within the required failure response time,

immediately correct the problem before

proceeding.

DANGER

Eclipse ExtensoHeat Lance Burners, V1, Installation Guide 235, 5/23/2011

Operating Cycle

Firing Zone (in roof)

For each group:

• Manually start the combustion air blower

• Check that the air actuator is closed

• Open the manual air and gas valves for each burner

• Press the main group start button. Air is set to

maximum and the burner main group safety

solenoid valve opens

• Temperature regulation takes place according to

selected type and mode

NOTE: During burner operation, the air flow is always

constant. The regulation cycles only take place with “car

stopped”. During each “car advance” the main group

safety valve closes, and the air actuator closes.

Stop

• Press the group(s) stop button

• Close the main and burner manual gas valve (firing

zone in kiln’s roof)

• If the kiln is maintained in operation, remove the

burners and close the holes

• In case of kiln stop, do not switch off the combustion

blower until the kiln temperature is less than 572ºF

(300ºC) and then close the air valves for each

burner

• Switch off the electrical power

NOTE: Keep the blower running after the burner is turned

off to protect the burner and other components from any

back flow of hot gases.

■ The following must be immediately carried out in

case of main power failure:

■ Close all manual air valves so that the burners are

isolated from the distribution manifolds and

prevent the return of hot gases through the

burners.

■ In case of a long power failure (more than 15

minutes), the burners should be removed from

their positions to prevent them from being

exposed to high temperatures for a prolonged

period.

■ Select resistant material for air pipes if there is a

possibility of temporary reversal of hot gases.
